INo. 856,976.

specification of Letters Patent.

Patented June 11, 1907.

-To all-whom it may concern:

i Be it known that I, HEZEKIAH MILLER, a citizenof the 4U'aited States, residing at Fort Morgan, in the county oi Morgan and State ofColoradoyhave invented a new and useful Nut-Loek, of which the following is a speciviication.

This invention relates to nut locks, more particularly to that class employing a superimposed nut; and the object thereof is to provide a deviceof this character that will be cheap, durable, effective and easy of manipulation.

.The invention .consists in the construction, combination and arrangement of parts hereinafterully described and claimed, and illustrated in -the accompanying drawings, in 'hlhy-jj Figure l1 is a side elevation of a bolt equipped with ajnut lock constructed in accordance with this' invention; Fig. f3 is a side elevation of the bolt; and Fig. 3 shows .an end elevation of the lock nut.

Referring. to the drawings, it is seen that the bolt 1 is provided with the usual head 2 at one end and has its opposite end provided with the usual righthand threaded l. .irt- 1 3 and the usual primary nut 4, and, in addii i, a reduced outerl extrei'nitj,- 5 provided will; left-hand threads land carrying the loi-.Li nut 6.

The lock 'nut/6 is provided upon its inner side with a/ 'laterallyextending flange 7 formed either integral with said lock nui. or by means of a Washer riveted to the nut: this flange is preferably-circular in shape and of a diameter slightly greater than the long di- ,y

arneter ,of the Aprimary nut, ,z-d is provide-d near its periphery with a series of uniformly spaced holes 8 adapted to receive a U-shaped .locking `pin 10, the' parallel ends :ai: the pin @gassin through alternate holes of the flange. To ock the primary nut the look nut' is sarewed down against it, binding it rainst nut adapted to dis laoement by the well-known action ofthe rig t and left-hand threads, and the lock nut itself is secured against displacement by means of the U-shaped locking in Which is inserted through the lock nut end oriover an angle of the primary nut so as to bear against a side or adjoining sides of said nut. The ends of the lock pin may be bent slightly after insertion so as to secure the pin in position, thus completing the operation of locking the primary nut.

Having thus fully described the invention, what is claimed and desired tofbe secured by Letters Patent is 2- l. In a nut lock the combination of a bolt, a primary nut thereon, a lock nut provided with a laterally extending flange on its inner end. and having a circular series of spaced holes within the periphery oi' said flange, and a locking pin adapted to engage a plurality of said holes and Ibe bent into contact Wlth 4the primary nut.

In a nut lock, the combination of a bolt provided with right and left-hand threads, a primary nut adapted to fit upon the ri hthand tlueadediportion of said bolt, a ook fit upon the left-hand threaded portion of said nut'and provided with a laterally-extending circular flange of a diameter slightly greater than the longI diameter :t the. primary nut and having `uniformly spaced .holes arranged about the periphery of said flange, and a U-shaped lookin pin adapted to engage in alternate holes o said flange, substantially as described and for the nlrpose set forth.

In testimonythat I claim the foregoing as my own, I have hereto atlixed my signature in tire presence of two Witnesses.
